Description

Seat post assemblies

Technical field

This provisional application relates generally to the seat of bicycle, and more particularly relate to bicycle seat can Adjust seat post assemblies.

Background technique

Bicycle can be equipped with the component of such as adjustable seat component etc.Such component can be advantageously allowed certainly Saddle is selectively reduced and increases when driving operation.For example, when the bigger control by being realized with bigger motion range is oblique When declining on slope, rider can benefit from lower saddle height.On the contrary, when by allowing bigger power to be transmitted to bicycle transmission When the position of system rises on the slope, rider can benefit from higher saddle height.Pass through the choosing of permission saddle during operation Selecting property height adjustment, the condition that bicycle is configured to variation provide seat position appropriate.

Typical bicycle seat component can have seat support strut, which is mechanically clamped to the seat of bicycle Pipe.Clamping piece can be fastener or bar, is released and promotes to glide on seat support strut to allow the internal diameter for increasing seat pipe It is dynamic, to adjust saddle height.In bicycle operation, such seat-assembly is not easy to adjust user friendlyly.For certainly The adjustable seat component of driving may be designed to relatively quickly adjust saddle height in restriction range.Such system is usual It is referred to alternatively as dropper seat support strut (dropper seat post), and can also be improved during operation using long-range activation Availability.Such long-range activation can be activated by cable strain, hydraulic pressure, electronic signal or other actuating methods.Far Journey activates the movement that can trigger in linear movement mechanism.Linear movement mechanism can include: spring, such as helical spring or pneumatic bomb Spring；Electronic device, such as servomechanism or motor；Or another type of linear actuators or its component.Such linear movement machine Structure is designed to provide power (as reversible electric motor) for the movement for increasing direction with reducing in the two of direction, or Person's linear movement mechanism such as can provide biasing only in one direction with spring.Such as, it is possible to provide pneumatic spring is with foot Enough power upwardly biases seat-assembly in raising side, so that saddle height can be increased by activating, while rider is not to saddle Seat applies downward force, but with being compared to the smaller power of gravity in the rider's mass for being applied to saddle, so that rider Weight can be used for reducing saddle height.Locking mechanism be can provide to prevent actuation wire movement mechanism, thus in fixed saddle Stable seat platform is provided at seat height degree.

When system quiescence and when not activating, the hydraulic locking mechanism for the adjustable seat component that raising side upwardly biases can Seat-assembly is provided and is increasing the positive support on direction.Compared with the system for using ratchet or pawl type locking mechanism, hydraulic lock Determining mechanism can provide more fine-tuning for saddle height.Hydraulic locking mechanism also avoids the problem that being associated with frictional locking mechanism (such as sliding).Hydraulic locking mechanism can be by (being referred to alternatively as convenience's sake with minimum compressible or incompressible fluid Incompressible fluid) adjustable volume work to support the moveable part of seat-assembly.In general, Incoercibility will Hereinafter refer to the fluid such as constructed in hydraulic fluid or pressure transmission construction for insubstantial compressibility, state Or component.For example, the hydraulic fluid of a constant volume can be accommodated in the support chamber of seat-assembly, wherein volume control valves energy It selectively operates to allow volume adjusted.On the contrary, term " compressible " will refer to the fluid with relatively high compressibility, These fluids transmitted such as under gaseous state or by generally interference hydraulic pressure.

A part of hydraulic fluid can be forced to store by the source of potential energy (pneumatic spring such as compressed) of release storage Device volume enters support chamber to increase adjustable volume, thus increases and is contained in the indoor volume of support chamber and increases saddle Highly.In this case, if when the power that rider's weight acts on support chamber is more than to be applied to storage by pneumatic spring Volume control valves are opened when power on storage volume, support the volume of chamber and saddle height that will reduce.Pass through adjustment portion The pressure or worksheet area of part, power needed for overcoming the spring biases strength can be adjustable.

Due to the entrance of compressible fluid, the hydraulic system dependent on hydraulic fluid Incoercibility can make reduced performance. For example, the gas for being present in atmosphere or being contained in the pneumatic spring of adjustable seat component can enter hydraulic pressure support chamber. Under stress, these compressible fluids will compress and allow the deflection of adjustable seat component.On the contrary, can advantageously be present Not or with very small movement in chair component, such as promote the more effective energy transmission with bicycle drivetrain.Because can The entrance that gas occurs in hydraulic system, for may be advantageous from the facility of this system release gas.It is such to ask Topic may also appear in other hydraulic units of bicycle, such as can also apply the front suspension component and rear suspension of this facility Component.

Actuated chambers 62 can use (such as electromechanical motor, cable actuation means or other actuating facilities) generation of actuation means 63 It replaces.The power that upper support surface 49 can be on raising direction B can apply multiple surfaces on it.Upper support surface 49 is at least A part can be the component in addition to seat support strut top 20.For example, actuating component 60 may act as the one of support surface 49 Part, as shown in the figure.Actuating component 60 can optionally be operated to allow such as compressible fluid by actuating 52 fluid of valve It is communicated in hydraulic heat exchanger chambers 58.

Fig. 6 to Fig. 8 illustrates the enlarged drawing of the discharger of Fig. 5 under various modes of operation.In one embodiment The component reverse bias retainer 90 of Fig. 3 can be omitted, and component 74 is discharged can inhibit and reverse bias direction E is moved past by another component On a bit.For example, actuating component 60 can prevent from making to be discharged component 74 on the E of reverse bias direction by contacting with discharge component 74 It is mobile.Discharge component 74 can stop in such a manner, to prevent discharge proximal seal 78 from crossing discharge proximal seal It is moved on the E of reverse bias direction on surface 88.

Discharge bias unit 80 can be also omitted in one embodiment, and acts at least one of discharge component 74 Pressure on point can bias discharge component 74 on biased direction D.For example, the pressure in hydraulic heat exchanger chambers 58 can be in biasing side It is applied a force upon on D on discharge component 74.In the case where any operating force is not present on the E of reverse bias direction, which can make Component 74 is discharged to move under release conditions, in the released state, component biases retainer 84 and inhibits by interference discharge main body 96 Further movement on biased direction D.Discharge main body 96 can be separation unit or can be a part of another component.Example Such as, discharge main body 96 can be a part of seat support strut head 18.Alternatively, discharge main body 96 can be detachable part and It can be sealed with discharge body seal 98.

Fig. 6 illustrates the enlarged drawing of the discharger 66 of Fig. 5 under release conditions.In the release of the illustrative embodiments Under state, main body 96 is discharged and biases 84 applied force of retainer to component on the E of reverse bias direction to offset by hydraulic heat exchanger chambers The power on biased direction D that pressure in 58 generates.In the released state, discharge chamber 82 can be with hydraulic 58 fluid of heat exchanger chambers Connection.Alternatively, discharge chamber 82 can be sealed relative to hydraulic heat exchanger chambers 58 in the released state, and in release conditions Start to be in fluid communication with hydraulic heat exchanger chambers 58 under the transition state (not shown) before intermediate state later.Such as Fig. 7, in Between under state, the fluid communication being discharged between chamber 82 and hydraulic heat exchanger chambers 58 is sealed.For example, component biases retainer 84 It can be formed and be tightly connected with discharge main body 96 in the released state, but the sealed connection can be interrupted under the transient state to promote The fluid communication that feed liquor is pressed heat exchanger chambers 58 and is discharged between chamber 82.In this example, hydraulic heat exchanger chambers 58 will be discharged Start to be in fluid communication with discharge chamber 82 before proximal seal 78 and discharge proximal seal surface 88 are in sealing contact, as in Between under state.

The compressible fluid being contained in hydraulic pressure support chamber 48 can be by hydraulic heat exchanger chambers in hydraulic pressure support chamber 48 The relative positioning and opening of top activate valve 52 and are discharged into hydraulic heat exchanger chambers 58 during release conditions.Exemplary In embodiment, the relative positioning is realized by the way that seat component 15 to be installed on bicycle 10, while bicycle is straight Vertical and be positioned on outer surface 42, wherein outer surface 42 is level ground as shown in Figure 1.It alternatively, can be such as in other realities Apply the in direct fluid communication for equally promoting hydraulic pressure support chamber 48 in mode and being discharged between chamber 82.

Fig. 7 illustrates the enlarged drawing of the discharger 66 of Fig. 5 under intermediate state.In this state, inhibit hydraulic Fluid communication between heat exchanger chambers 58 and discharge chamber 82.Be discharged proximal seal 78 and discharge proximal seal surface 88 it Between sealed connection can inhibit the fluid communication.In an intermediate state, it further suppresses fluid communication and crosses the sealing of discharge distal side Part 76.It is tightly connected for example, discharge distal seal 76 can be formed with discharge distal seal surface to inhibit the fluid to connect It is logical.Discharge distal seal 76 and discharge distal seal surface 86 it is in sealing contact and be discharged proximal seal 78 and discharge While proximal seal surface 88 contacts, intermediate state may be present.During intermediate state, the fluid of fixed volume can be accommodated In discharge chamber 82.The fixed volume can be it is adjustable, with during actuating state realize compressible fluid maximum release Put the balance between pressure and the minimum release of incompressible fluid.

Fig. 8 illustrates the enlarged drawing of the discharger 66 of Fig. 5 under actuating state.Under the actuating state shown, Discharge component 74 is not contacted with actuating component 60.Actuating component 60 can be used for stopping by actuating state point along reverse bias direction E Movement or component reverse bias retainer 90 standalone embodiment can be set to limitation discharge component 74 operational stroke. Under the actuating state shown, discharge distal seal 76 is not in sealing contact with discharge distal seal surface 86, thus passes through The fluid communication of discharge distal seal 76 is possibly realized.Fluid communication by distal seal 76 is discharged can be discharge chamber Fluid communication between room 82 and external volume 100 (such as atmosphere).It is assumed that and atmosphere, fluid will be in actuating state Under from discharge chamber 82 discharge, until discharge chamber 82 equilibrated to atmospheric pressure.

Fluid communication by distal seal 76 is discharged may be additionally located at another component of discharge chamber 82 and bicycle 10 Or between another component of seat component 15.For example, discharge chamber 82 can be by discharge distal seal 76 and another component stream Body connection, in order to accommodate fluid and/or recirculated fluid.The fluid by distal seal 76 is discharged can also be further suppressed Connection.It is sealed for example, discharge distal seal surface 86 can be formed with another part of the distal end 67 of discharge component 74, to limit System is in fluid communication.In this example, the interaction of discharge component 74 and discharge distal seal surface 86 can inhibit dense stream The flowing of body (such as oily), while allowing the flowing of the smaller fluid of color density (such as atmospheric gas).This exemplary possibility Construction may include gas-liquid separation device (such as hydrophobic porous polymer film), and gas is allowed to flow therethrough, but prevent fluid It flows therethrough.

Discharger 66 can further comprise flow device 101.Flow device 101 can be configured to permeable means 102 are fixed to a part of seat component 15.For example, flow device 101 can threadingly be attached to seat support strut head 18 In with permeable means 102 are fixed between them.Permeable means 102 can be flexible to be sealingly attached to it In, or may be provided with individual seals (not shown) to seal permeable means 102.Permeable means 102 can be with hydraulic friendship Change 58 in direct fluid communication of chamber.Flow device 101 is permeable at least some fluids.For example, flow device 101 can have There is flow unit 103, can be a channel, multiple channels or other for allowing to be in fluid communication and promote flow structure.By Any fluid communication of permeable means 102 and/or flow device 101 can be located at the component and external volume of seat component 15 Between 100, or between the component positioned at seat component 15 and another component of seat component 15.For example, permeable means 102 It can promote the fluid communication between hydraulic pressure support chamber 48 and external volume 100.

Figure 11 illustrates the enlarged drawing of the alternative embodiment of discharger 66.Example and Fig. 2 in Figure 11 is into Fig. 8 It is exemplary the difference is that, it includes permeable means 102 and flow device 101 (can be identical with Figure 10).In Figure 11 Example is with the exemplary difference part in Figure 10, is added to the second discharge component 174.Second discharge component 174 can As being in fluid communication in Figure 11 with hydraulic pressure support chamber 48, and/or according to being arranged through permeable means shown in Figure 10 102 and/or flow device 101 and hydraulic heat exchanger chambers 58 be in fluid communication.In such relationship, the illustrative embodiments The associated member of second discharge component 174 and discharger 66 can be described as inferior to permeable means 102 and/or flow device 101 mainly be in fluid communication.Alternatively, the second discharge component of no permeable means 102 and/or flow device 101 can be used 174, and the discharge component 74 in conjunction with permeable means 102 and/or flow device 101 can be used.

Second discharge component 174 can be biased on biased direction D by the second discharge bias unit 180.Second discharge biasing Device 180 can be spring (helical spring in such as present embodiment), or can be and operating pressure is promoted to act on the Construction on the surface of two discharge components 174.Second discharge bias unit 180 can bias the second discharge structure on biased direction D Part 174 stops until by another component (such as second component biases retainer 184).Second component biases retainer 184 can It is formed and is tightly connected, sealing element 178 and second row is discharged in the second component biasing retainer 184, second of such as discharger 66 Sealed connection between main body 196 out.Second discharge component 174 can be limited to second component reverse bias on the E of reverse bias direction Retainer 190.Second component reverse bias retainer 190 can be fixed or can dismantle and can be and be adjustable.

Second discharge main body 196 can be from the disassembly of seat component 15 or as the integrated component of seat component 15.Seat portion Pressure in part 15 can overcome the second discharge bias unit 180 so that the second discharge component 174 shifts and allows by second The fluid communication of sealing element 178 is discharged.For example, from seat support strut top 20 relative to seat support strut lower part 22 along reduction direction The pressure of the movement of C can cause in the hydraulic pressure support chamber 48 transmitted via permeable means 102 and/or flow device 101 Pressure be enough by the working surface that acts on the second discharge component 174 and thus make the displacement of the second discharge component 174 come gram The second discharge bias unit 180 is taken, to promote by the second discharge sealing element 178 and the fluid communication with external volume 100. Such as receiving shown in Figure 12 or the purpose recycled, such stream can also be carried out with another component of seat component 15 Body connection.

Figure 12 illustrates the enlarged drawing of the alternative embodiment of discharger 66.Example in Figure 12 is with the one shown in figure 11 It is exemplary the difference is that, by second discharge sealing element 178 fluid communication be located at hydraulic pressure support chamber 48 (process can seep Saturating device 102 and/or flow device 101) and pneumatic spring chamber 46 (being overregulated path 70 and/or recirculation path 104) Between.In this way, gas can be discharged from hydraulic chamber (such as hydraulic pressure support chamber 48 or hydraulic heat exchanger chambers 58), together When maintain seat component 15 internal pressure.

Figure 13 and Figure 14 illustrates the alternative embodiment of discharger 66.Example and Fig. 2 in Figure 13 and Figure 14 are extremely schemed Shown in 12 it is exemplary the difference is that, have discharge proximal seal 78 and be discharged distal seal 76 discharge component 74 are configured to operate in response to hydraulic pressure.For example, discharge component 74 can be configured in response to hydraulic pressure support chamber 48 In hydraulic pressure moved on the E of reverse bias direction along second axis M.Hydraulic pressure in hydraulic pressure support chamber 48 will act on In on all parts for the discharge component 74 being connected to hydraulic pressure support chamber 48.Discharger 66 is constructed such that hydraulic pressure support Pressure increase in chamber 48 will generate resulting net force on discharge component 74 along reverse bias direction E.Component reverse bias surface 75 can quilt It is configured to promote the resulting net force on the E of reverse bias direction.The other parts that hydraulic pressure can also act on discharge component 74 generate institute State resulting net force.For example, can have hydraulic pressure effect with the discharge chamber 82 of 48 pressure communication of hydraulic pressure support chamber on it One or more surfaces.

Hydraulic pressure may be from acting on the power on seat component 15 when activating valve 52 and being closed.For example, due to dropping The power on saddle 16 such as is acted on from rider on low direction C, seat support strut top 20 can be on reducing direction C towards seat Pillar lower part 22 pushes.The power increased on the B of direction can be acted on seat support strut lower part 22 by frame 12.In this example, The pressure in hydraulic pressure support chamber 48 generated by these power can be acted on the E of reverse bias direction on discharge component 74.

In addition, Figure 13 illustrates the embodiment without floating piston 44.Dependent on the fluid with different densities it Between Gravity Separation, such embodiment can keep similar characteristics.For example, relatively highdensity fluid oil will with it is opposite It is collected at the gravitational base of given chamber when compared with the connection of the gaseous fluid of low-density.As an example, in seat component 15 Installing state under, relatively highdensity liquid hydraulic fluid by the compressed air or nitrogen separation with relatively low density, Wherein hydraulic fluid separates on reducing direction C and compressed air or nitrogen separate on increasing direction B.With such side Formula is, it can be achieved that the fluid similar with the embodiment with floating piston 44 distributes.

In this way, which is convenient for the indoor different fluid of disengagement chamber.For example, relatively highdensity liquid Body fluid and the gaseous fluid of relatively low density can be added to connecting chamber 112.Connecting chamber 112 can be configured so that phase The fluid of higher density will be separated in the hydraulic reservoirs part 250 of connecting chamber 112, and the stream of relatively low density Body will be separated in the pneumatic spring part 246 of connecting chamber 112.Chamber portion (such as pneumatic spring part 246 and hydraulic storage Latch portion 250) between separation can be limited by fluid relative level.

Discharge bias unit 80 can be used for providing bias force on discharge component 74 along biased direction D.The bias force can be with Be it is adjustable, make to be discharged component 74 to adjust and shift the amount of required reverse bias power on the E of reverse bias direction.For example, discharge is inclined Set device 80 can be for be applied to discharge component 74 make be discharged component 74 shift at anti-needed for actuating state (such as Fig. 8) Bias force is adjustable spring.Such as can be acted on discharge component 74 from the pressure that pneumatic spring chamber 46 transmits, inclined It sets and forms resulting net force on the D of direction, to facilitate bias force.It may include component offset surface 77 forming such resulting net force, or The other parts of discharge component 74 can be used in person.In this way, discharge bias unit 80 is adjusted in combination with the construction of discharge component 74 It is whole, to need the reverse bias power of enough size to make to be discharged the displacement of component 74 into actuating state.The power of the enough size can be with pressure It is poor related.For example, hydraulic pressure support chamber 48 and the given pressure difference adjusted between path 70 can operate discharge 74 mistake of component enough It crosses under actuating state.Then, the discharge chamber 82 and adjust path 70 which can correspond under the intermediate state such as Fig. 7 Or lead to pressure difference between another communication path of pneumatic spring chamber 46.

Discharge component 74 may also include offset liner 106 and/or reverse bias liner 108.For example, component biases retainer 84 It can be configured to accommodate offset liner 106 and reverse bias liner 108 with component reverse bias retainer 90.Offset liner 106 can be with It is compressible member (such as O-ring), which is configured to buffering discharge component and advances completely on biased direction D When impact.Reverse bias liner 108 can be compressible member (such as O-ring), which is configured to buffering row Impact of the component 74 when advancing completely on the E of reverse bias direction out.Offset liner 106 and reverse bias liner 108 can be also constructed It is formed and is tightly connected between discharge component 74 and discharge main body 96 at for example.Upper support surface 49 may be arranged at discharge main body Ramp formation can be presented in part on 96.For example, the ramp formation of the part of upper support surface 49 can promote fluid in seat Component 15 is flowed into when being under installing state on bicycle 10 in discharge chamber 82.

It can exist for transmitting the biasing chamber 110 for acting on the power on component offset surface 77 along biased direction D.Biasing Chamber 110 can be configured to for example be in fluid communication via recirculation path 104 and pneumatic spring chamber 46.In this way, From hydraulic pressure support chamber 48 via discharge chamber 82 lead to biasing chamber 110 fluid can be recycled and with pneumatic spring chamber 46 connections.As described above, pneumatic spring chamber 46 can be in fluid communication with hydraulic reservoirs chamber 50.

Biasing chamber 110 can be configured so that under installing state, biasing chamber 110 accommodates the liquid flow of capture volume Body.For example, biasing chamber 110 can limit the fluid communication via recirculation path 104 and pneumatic spring chamber 46.In actuating shape Under state, such as when the Fluid pressure being discharged between chamber 82 and biasing chamber 110 has been balanced, gravity can make to be contained in biasing Liquid fluid in chamber 110 is shifted through discharge distal seal 76 and enters discharge chamber 82.Gravity can be in release conditions Period is displaced to such fluid further in hydraulic pressure support chamber 48.Alternatively, from discharge chamber 82 by discharge distal side The fluid communication of sealing element 76 reaches external volume 100.

Figure 15 is the enlarged drawing of the alternative embodiment of seat component 15.Example and Fig. 2 showing into Figure 14 in Figure 15 Example the difference is that, be not provided with discharger 66.Alternatively, the embodiment in Figure 15 is integrated with collection device 366. Collection device 366 is configured to be in fluid communication with hydraulic heat exchanger chambers 58.Hydraulic heat exchanger chambers 58 and collection device 366 can be by structures Cause the flowing convenient for separation Jing Guo hydraulic heat exchanger chambers 58.For example, during the flow regime across actuating valve 52, by opposite Compared with the compressible fluid of low-density and the group interflow of relatively highdensity incompressible fluid composition can enter collection device 366。

Adjustable collection device 366 promotes separation in various ways.For example, collection device there can be enough volumes, use To reduce flow rate and promote the separation between the fluids of different densities.Separation can be generated by Gravity Separation, and phase Collection device 366 can be entered to the compressible fluid compared with low-density.Collection device 366 can also be constructed based on relative density and tie up Hold separation.For example, the flowing by collection device 366 can be limited, so that the separation group of the compressible fluid of relatively low density Dividing not enter from collection device 366, there is the group of fluid-mixing density to collaborate.In alternative embodiment, fluid can be for example with row Device 66 is discharged from collection device 366 out.

Figure 16 is the equal part cross-sectional view with an embodiment of seat component 15 for discharger 66.Seat component 15 further comprise sealing device 466.Actuated chambers 62 be may be provided with to promote actuating component 60 to move in response to hydraulic pressure It is dynamic.Actuating valve 52 is operated from sealing state for example, actuating component 60 may be in response to the increase of the Fluid pressure in actuated chambers 62 To unsealing state.Remote-control device 61 be may be provided with to promote the pressure change in actuated chambers 62.

Actuated chambers 62 and actuating component 60 can be a part of actuation means 63.Alternatively, actuation means 63 can wrap Include other actuating configurations, such as electromechanical motor, cable actuation means or other actuating facilities.Actuating component 60 optionally can Operation is to allow such as compressible fluid to be transmitted in hydraulic heat exchanger chambers 58 by actuating 52 fluid of valve.

Figure 17 illustrates the enlarged drawing of the sealing device 466 of Figure 16.Pneumatic spring regulating valve 64 is shown as having and adjust Valve deck 68.In the case where adjusting valve deck 68 and being disassembled, pneumatic spring regulating valve 64 can be operated to selectively promote and such as The fluid communication of the external component of air pump (not shown) etc.Fluid communication by pneumatic spring regulating valve 64 can be passed through further It overregulates path 70 and extends in pneumatic spring chamber 46.A part of hydraulic pressure support chamber 48 is shown as at least partly It is sealed by support chamber upper seal 72.At least part of discharger 66 is shown as flowing with hydraulic pressure support chamber 48 Body connection.

Discharge component 474 can advance along second axis M and be biased on biased direction D by discharge bias unit 480. Second axis M can be coaxial with first axle L, orthogonal or at some other relationship.In this way, biased direction D can be with raising direction B It is identical, or can be the other direction as shown in other embodiments.It is (all that discharge bias unit 480 can be spring Such as helical spring), or can be the construction on the surface for promoting operating pressure to act on discharge component 474.Component 474 is discharged It can have a first end and a second end.Be discharged component 474 these first end and second ends and with the associated component in these ends Relative to seat component 15 internal hydraulic pressure component (such as Figure 19 hydraulic heat exchanger chambers 58 or Figure 16 hydraulic pressure support chamber 48) distal side or nearside are referred to alternatively as.

Discharge component 474 can have the first retainer and the second retainer.For example, can to include component inclined for discharge component 474 Retainer 484 is set, is located at the proximal end of discharge component 474, to limit the movement on biased direction D；And component reverse bias Retainer 490 is located at the far-end of discharge component 474, to limit the movement on the E of reverse bias direction.Component biases retainer 484 and/or discharge component 474 can be configured to there is no be tightly connected in the case where promote flowing.

When under release conditions, discharge component 474 is by discharge sealing element 476 and seal surface 486 is discharged Interaction carrys out sealed hydraulic support chamber 48 without being connected to pneumatic spring chamber 46.In this embodiment, discharge sealing Part 476 is fixed in discharge component 474, so that operation of the discharge component 474 on the E of reverse bias direction can make that sealing element is discharged 476 shift on the reverse bias direction E along second axis M.Various ramp formations can be presented in discharge seal surface 486, with Abrasion between sealing state and non-tight state on transition period limitation discharge sealing element 476.

If such as being more than gas to overcome the power of discharge bias unit 480 to be enough the pressure in hydraulic pressure support chamber 48 Pressure in dynamic spring chamber 46, then component 474, which will be discharged, to be moved on the E of reverse bias direction.This movement of component 474 is discharged It will make the sealing interaction that the displacement of sealing element 476 disengaging and discharge seal surface 486 is discharged and thus allow hydraulic pressure support Fluid communication between chamber 48 and pneumatic spring chamber 46.Component reverse bias retainer 490 can be set to inhibit discharge component 474 movement on the E of reverse bias direction.In one embodiment, component reverse bias retainer 490 is partially due to the row of combination The helical spring of bias unit 480 constructs to inhibit to move out.In this example, component biasing retainer 484 limitation discharge structure Operational stroke of the part 474 on biased direction D, and the limitation discharge component 474 of component reverse bias retainer 490 is in reverse bias side Operational stroke on E.

Discharge bias unit 480 can be used for providing bias force on discharge component 474 along biased direction D.The bias force can Be it is adjustable, make to be discharged component 474 to adjust and shift the amount of required reverse bias power on the E of reverse bias direction.For example, discharge Bias unit 480, which can be, shifts into actuating state (such as Figure 25) institute the component 474 that makes to be discharged for being applied to discharge component 474 The reverse bias power needed is adjustable spring.Such as can be acted on discharge component 474 from the pressure that pneumatic spring chamber 46 transmits, To form resulting net force on biased direction D, to facilitate bias force.It may include that component offset surface 477 is such to be formed Resulting net force, or the other parts of discharge component 474 can be used.

Discharge bias unit 480 is adjusted in combination with the construction of discharge component 474, to need the reverse bias of enough size Power makes to be discharged the displacement of component 474 into actuating state.The power of the enough size can be related to pressure difference.For example, hydraulic pressure support chamber Given pressure difference between 48 and pneumatic spring chamber 46 can operate discharge component 474 enough and be transitioned under actuating state.Then, The pressure difference can correspond to hydraulic pressure support chamber 48 and biasing chamber 401 or lead to another communication path of pneumatic spring chamber 46 Between pressure difference.Discharge bias unit 480 can be adjusted further to overcome frictional force, such as discharge sealing element 476 and discharge Friction between seal surface 486.

Biasing chamber 410 can be used for transmitting the power acted on component offset surface 477 along biased direction D.Biasing chamber 410 can be configured to for example be in fluid communication via recirculation path 404 and pneumatic spring chamber 46.In this way, from liquid The fluid that pressure support chamber 48 leads to biasing chamber 410 can be recycled and be connected to pneumatic spring chamber 46.As described above, gas Dynamic spring chamber 46 can be in fluid communication with hydraulic reservoirs chamber 50.

Biasing chamber 410 can be configured so that under installing state, biasing chamber 410 accommodates the liquid flow of capture volume Body.For example, biasing chamber 410 can limit the fluid communication via recirculation path 404 and pneumatic spring chamber 46.In actuating shape Under state, and when the Fluid pressure being discharged between chamber 82 and biasing chamber 410 has been balanced, gravity can make to be contained in biasing Liquid fluid in chamber 410 is shifted through discharge sealing element 476 and enters hydraulic pressure support chamber 48.Alternatively, from hydraulic branch It supports chamber 48 and reaches external environment 100 by the fluid communication of discharge sealing element 476.

Discharge bias unit 480, which can be, to be adjustable.For example, bias-adjusted component 410 may be present.Bias-adjusted component 410 are configured to adjust the power for being applied to discharge component 474 by discharge bias unit 480.Bias-adjusted component 410 can such as with Adjustable pneumatic spring or the captured helical spring construction that bias unit 480 is discharged and discharge bias unit 480 are integrally.Separately Selection of land, bias-adjusted component 410 can be the component discrete with discharge bias unit 480.

As shown in figure 17, bias-adjusted component 410 can have removable bias regulator 412.Removable bias regulator 412 can move to adjust the power for being applied to discharge component 474 in biased direction D by discharge bias unit 480.For example, removable Bias regulator 412 can be moved on biased direction D to increase the power for being applied to discharge bias unit 480 on biased direction D, And it can also be moved on the E of reverse bias direction to reduce the power for being applied to discharge bias unit 480 on biased direction D.One In a illustrative embodiments, the helical spring construction that removable bias regulator 412 can promote discharge bias unit 480 is independent In the compression and extension of the movement of discharge component 474.

Removable bias regulator 412 can promote threadingly engage fortune with another component of seat component 15 It is dynamic.For example, removable bias regulator 412 can have thread regulator part 415, thread regulator part 415 is configured to It is engaged with the thread head part 413 of seat support strut head 18.The screw pitch of thread regulator part 415 and thread head part can be constructed At inhibit they between as the E of reverse bias direction on from be discharged bias unit 480 power caused by relative motion.Discharge biasing Device 480 can be adjusted with interface 414 is adjusted.Adjusting interface 414 can be tool interface such as with hex nut, Huo Zheke To be manual interface such as with annular knurl.

It may be provided with and adjust reverse bias retainer 416 and/or adjust biasing retainer 420, adjusted with limiting removable biasing Save the movement of device 412.Adjusting reverse bias retainer 416 can be set to limit the movement on the E of reverse bias direction, and adjust biasing Retainer 420 can be set to the movement on limitation biased direction D.Adjusting retainer 416,420 can be by any appropriate rigid material Material or combination of materials are formed.It can be by one of aluminium, steel, nylon and vinyl or a variety of systems for example, adjusting retainer 416,420 At.Adjusting retainer 416,420 can be integrally formed with another component of seat support strut head 18 or seat component 15.Show at one In example property embodiment, adjusts biasing retainer 420 and be the lower surface of seat support strut head 18, and adjust reverse bias retainer 416 be the locking device in the recess portion of seat support strut head 18.For example, adjusting reverse bias retainer 416 can be by groove The locking ring or circlip being located in seat support strut head 18.

Adjustable range can be limited based on possible position of the bias-adjusted component 410 between adjusting retainer 416,420. Adjustable range can correspond to the range that the power of discharge component 474 is applied to by discharge bias unit 480.For example, being biased by discharge The power that device 480 is applied to discharge component 474 may correspond to the adjustable range end of adjusting reverse bias retainer 416 most It is small.The minimum force can be relatively low power or zero-g.Alternatively, stop when bias-adjusted component 410 against reverse bias is adjusted When moving part 416 stops, bias unit 480 is discharged or another component can be on the E of reverse bias direction to discharge 474 applied force of component.

In this way, when removable bias regulator 412 adjust closer to adjust reverse bias retainer 416 When, discharge component 474 can more easily be transitioned into its opening state.Removable bias regulator 412 can be used as a result, to allow User purposefully changes between the state relatively easily discharged.Correspond to for example, removable bias regulator 412 can have Position in the adjustable range of rider's weight, landform and/or riding style.Removable bias regulator 412 may also include anti- The only position in the adjustable range of the movement of discharge component 474 or locking.

In some cases, it may be useful for preventing actuating discharge component 474.Actuating discharge component 474 may cause Thus the fluid loss of hydraulic pressure support chamber 48 leads to the unexpected phase between seat support strut top 20 and seat support strut lower part 22 To movement.As described above, removable bias regulator 412 can be configured to inhibit discharge component 474 in its adjustable range Operation at least one position.Locked can also be had by moving bias regulator 412 as a result,.

Pneumatic spring regulating valve 64 can also be integrated with bias-adjusted component 410 or be installed to bias-adjusted component 410.Example Such as, pneumatic spring regulating valve 64 can be presented Schrader construction and integrate with bias-adjusted component 410.Bias-adjusted component 410 It is also configured to receive for example to install by thread attachment interface to adjust valve deck 68.

The pressurized fluid of one constant volume can be discharged from hydraulic pressure support chamber 48 by discharge sealing element 476.Such arrangement It can be configured so that the position separated between compressible fluid and the group interflow of incompressible fluid occurs for release.Example Such as, the seat component 15 that can be mixed with the incompressible fluid of relatively large density in the compressible fluid of relatively small density In construction, optionally allow the raised position from the compressible fluid for collecting smaller density (such as adjacent to upper support surface 49) it discharges.Seat component 15 can be configured to create such position effectively to collect relatively small density fluid or divide The component at the group interflow from different fluid density.In alternative embodiment, discharge sealing element 476 and discharge seal surface 486 can be configured in the released state in sealing contact.

Sealing unit 424 can be solid parts or can have hollow structure.For example, sealing unit 424 can be by Solid parts made of the material of opposite intermediate density, or there is the sealed body made of relatively highdensity material 426 hollow part.The hollow structure of sealed body 426 surrounds body interior 428.Body interior 428 can be accommodated in close Seal the relatively low density fluid in main body 426.

Sealing device 466 may include one or more surfaces being arranged in hydraulic pressure support chamber 48.For example, upper support At least part on surface 49 can be a part of sealing device 466.Sealed body 426 can be configured to and upper support surface 49 hermetically interact.A part of upper support surface 49 or another surface inside hydraulic pressure support chamber 48 can form main body Interactive surfaces 430, main body interactive surfaces 430 are configured to hermetically interact with sealed body 426.Main body phase Interaction surface 430 can be configured to guide sealing unit 424 at sealing state.For example, main body interactive surfaces 430 can To be frusto-conical configuration, so that the bulbous configuration of sealing unit 424 moves on increasing direction B with sealing unit 424 And it is directed into sealing station.

Sealed body 426 can be configured to hermetically interact with main body interactive surfaces 430.For example, when sealing For unit 424 relative to hydraulic pressure support chamber 48 when moving on increasing direction B, sealed body 426 can be with main body interaction table Face 430 hermetically interacts.Due to the buoyancy of fluid composition and sealing unit 424 in hydraulic pressure support chamber 48, sealing is single Member 424 can move on increasing direction B.

Sealing unit 424 fills top-uping for the relatively high density fluid of hydraulic pressure support chamber 48 about filling or generally Power can lead to sealed body 426 and hermetically interact with main body interactive surfaces 430.When sealed body 426 and main body phase When interaction surface 430 forms sealing interaction, it may be determined that fill the threshold percentage of relatively high density fluid.Sealing master At least one of body 426 and main body interactive surfaces are deformable and form sealing interaction.Sealed body 426 can also have There is smooth surface smoothness, the smooth surface smoothness with main body interactive surfaces 430 can be sealed operatively.Sealing Main body 426 and the smooth surface smoothness of the correspondence of main body interactive surfaces 430 can form metal to metal seal.Flow of pressurized The shallow layer of body can microscopically interact in such metal to metal seal with auxiliary seal.In an embodiment In, when sealing unit 424 is in hydraulic pressure support chamber 48 along the limit of sports record for increasing direction B, it is suppressed that from hydraulic pressure support Chamber 48 is via biasing chamber 401 to the fluid communication of recirculation path 404.

Sealing unit 424 can lead to sealing master about the negative buoyancy force of the relatively low density fluid in hydraulic pressure support chamber 48 Body 426 does not interact hermetically with main body interactive surfaces 430.For example, the air or gas in hydraulic pressure support chamber 48 Sealing unit 424 can be made to shift on reducing direction C relative to hydraulic pressure support chamber 48.In this way, work as hydraulic pressure support When being seldom with or without the compressible fluid of relatively low density in chamber 48, the optionally sealed hydraulic of sealing unit 424 Support chamber 48.

In addition to discharger 66 or discharger 66 is substituted, may be provided with sealing unit 424.For example, Figure 16 can be omitted In discharger 66, and can by sealing device 466 adjust from hydraulic pressure support chamber 48 by biasing chamber 401 flow direction follow again The flowing of endless path 404, as shown in figure 31.The adjusting of above-mentioned discharger 66 can be used for adjusting the function of sealing device 466.Example Such as, it is not to move out and discharge seal surface 486 corresponding to the position lockable discharge component 474 for adjusting biasing retainer 420 It is in sealing contact.In this embodiment, the fluid communication lacked across discharge sealing element 476 will inhibit sealing device 466 Function.It can promote the relatively easy or uncontrolled of discharge component 474 corresponding to the position for adjusting reverse bias retainer 416 Operation equally promotes the operation of sealing device 466 when being in fluid communication across discharge sealing element 476.

The main body interactive surfaces 430 of sealing device 466 can be located at the other component with composition hydraulic pressure support chamber 48 On isolated component.For example, main body interactive surfaces 430 can be a part of housing member 432.Housing member 432 can It is formed and is sealed with the inner surface 434 of hydraulic pressure support chamber 48.For example, may be provided with housing seal 436 with housing member 432 It hermetically interacts with inner surface 434.Housing seal 436 can be elastic sealing element, such as O-ring.

Hydraulic pressure support chamber 48 may be characterized as with discharge unit 438 and hermetic unit 440.Discharge unit 438 represents The part for being higher than the horizontal P of dense fluids on the B of direction is increased, and hermetic unit 440 is on reducing direction C lower than high density The part of fluid levels P.The horizontal P of dense fluids be hydraulic pressure support chamber 48 in relatively highdensity incompressible fluid and Boundary between the incompressible fluid of relatively low density.For example, if not having in hydraulic pressure support chamber 48 relatively low close Fluid is spent, then the horizontal P of dense fluids may be not present in hydraulic pressure support chamber 48.

The relative density of sealing unit 424 can be adjustable.It is slightly less than for example, sealing unit 424 can be adjusted to density The density of relatively high density fluid in hydraulic pressure support chamber 48.The density of sealing unit 424 can be adjusted to so that sealing master Body 426 do not enter it is in sealing contact with main body interactive surfaces 430, until the horizontal P of dense fluids increase direction B on foot Enough height are sealed in minimum relatively low density fluid in hydraulic pressure support chamber.Sealing unit 424 can be configured so that Sealing interaction does not occur between sealed body 426 and main body interactive surfaces 430, until no relatively low density current Body is maintained in hydraulic pressure support chamber 48, and thus the horizontal P of dense fluids is not present.

Figure 18 illustrates the enlarged drawing of the sealing device 466 of Figure 16.Diagrammatically showing in its unsealing shape in Figure 18 Discharge component 474 under state.When actuating valve 52 is under its closed state, as the power reduced on the C of direction is via saddle 16 It is applied to seat support strut top 20, the Fluid pressure acted on support surface 49 increases.It is acted on when on the E of reverse bias direction The power (acted on upper support surface 49 at least partially) on discharge component 474 is more than to be applied by discharge bias unit 480 When pressure in the power and biasing chamber 401 on biased direction D, discharge component 474 will move on the E of reverse bias direction. If the power on the E of reverse bias direction continues the power being greater than on biased direction D, component 474, which is discharged, will enter its unsealing state.

As the pressure in hydraulic pressure support chamber 48 continues more than the pressure in biasing chamber 401 and by discharge bias unit 480 the sum of the power applied, fluid will flow to biasing chamber 401 from hydraulic pressure support chamber 48.The compressible flow of relatively low density Body will flow into biasing chamber 401 due to Gravity Separation and preferentially.In the present embodiment of discharger 66, along reverse bias side To E act on discharge component 474 on power be more than along biased direction D act on discharge component 474 on power this state under, Relatively highdensity compressible fluid can continue to flow out hydraulic pressure support chamber 48.

Figure 19 is a reality of the seat component 15 of Figure 16 in the case where sealing device 466 is under its sealing state Apply the equal part cross-sectional view of mode.Sealing device 466 is shown under its sealing state, to inhibit relatively highdensity Incompressible fluid flows into biasing chamber 401 from hydraulic pressure support chamber 48.With the fluid displacement in hydraulic pressure support chamber 48 Reduce, sealing device 466 enters its sealing state.For example, when activate valve 52 be under its sealing state when and work as fluid from When hydraulic pressure support chamber 48 flows to biasing chamber 401, the fluid displacement in hydraulic pressure support chamber 48 will reduce.

When sealing unit 424 is under its sealing state, a part of sealed body 426 can form support surface 49 A part.Pressure in hydraulic pressure support chamber 48 can act on sealed body 426, to apply sealing force along raising direction B It is added on sealing unit 424.Pressure can force sealed body 426 and main body interactive surfaces 430 in sealing contact as a result,.? Increased pressure can act in hydraulic pressure support chamber 48 under the state, such as by forcing sealed body 426 and main body phase At least one of interaction surface 430 flexible deformation increases between sealed body 426 and main body interactive surfaces 430 Seal the surface area of interaction.

Discharge bias unit 480 can be omitted in one embodiment, and acts at least one of discharge component 474 Pressure on point can bias discharge component 474 on biased direction D.For example, the pressure in biasing chamber 401 can be along biased direction D is applied a force upon on discharge component 474.In the case where any operating force is not present on the E of reverse bias direction, which can make to be discharged Component 474 moves into release conditions, and in the released state, component biasing retainer 484 is inhibited by contacting with housing member 432 Further movement on biased direction D.Housing member 432 can be the component of separation or can be one of another component Point.For example, housing member 432 can be a part of seat support strut head 18 or seat support strut top 20.Alternatively, housing member 432 can be detachable part and can seal with housing seal 436.

Being contained in the compressible fluid in hydraulic pressure support chamber 48 can be by biasing chamber 401 on hydraulic pressure support chamber 48 Side relative positioning and be discharged into during release conditions in biasing chamber 401.In the exemplary embodiment, described relatively fixed Position is realized by the way that seat component 15 to be installed on bicycle 10, while bicycle is upright and is positioned in outer surface 42 On, wherein outer surface 42 is level ground as shown in Figure 1.

Figure 20 is illustrated in the case where bias-adjusted component 410 is in the minimum state for corresponding to and adjusting reverse bias retainer 416 In the case where Figure 16 sealing device 466 enlarged drawing.Under the minimum state of bias-adjusted component 410, discharge biasing Device 480 is under minimum force state, and under minimum force state, the power of discharge component 474 is applied to by discharge bias unit 480 Size be less than bias-adjusted component 410 any other position.Under the minimum state of bias-adjusted component 410, actuating The power difference needed for component 474 between hydraulic pressure support chamber 48 and biasing chamber 401 is discharged and is less than appointing for bias-adjusted component 410 What other positions.

Above-mentioned flow regime also can be described as the function of hydraulic pressure.Hydraulic pressure may originate from the work when activating valve 52 and being closed With the power on seat component 15.For example, due to such as acting on the power on saddle 16, seat from rider along reduction direction C Column upper section 20 can be pushed towards seat support strut lower part 22 along direction C is reduced.The power increased on the B of direction can be made by frame 12 With on seat support strut lower part 22.In this example, the pressure in hydraulic pressure support chamber 48 generated by these power can be along reverse-biased Direction E is set to act on discharge component 474.

Figure 21 illustrates the enlarged drawing of the sealing device 466 of Figure 16.Compared with Figure 20, Figure 21's is diagrammatically shown in it Discharge component 474 under actuating state.The actuating state utilizes the bias-adjusted component 410 under its minimum state is opposite to hold It changes places realization, because being more than to act on discharge along biased direction D along the power that direction C is acted on seat support strut top 20 is reduced Power on component 474.When sealing device 466 is under its unsealing state, promote hydraulic pressure support chamber 48 and biasing chamber Fluid communication between 401.Seat component 15 can be configured to make due to Gravity Separation from discharge unit 438 relatively Low density flow preferentially flows to biasing chamber 401 from hydraulic pressure support chamber 48.As fluid flows through discharge sealing in this way The volume of part 476, discharge unit 438 will reduce and sealing unit 424 will be closer to main body interactive surfaces 430.

Figure 22 illustrates the enlarged drawing of the sealing device 466 of Figure 16, the progress of the diagram as Figure 21, wherein seat support strut Continue to move along reduction direction C relative to seat support strut lower part 22 in top 20.In this illustration, it is close to be in its for sealing device 466 Under envelope state, sealed body 426 and main body interactive surfaces 430 are formed and are sealed.The embodiment shown is not by discharge portion 438 are divided to be maintained in hydraulic pressure support chamber 48, because all relatively low density fluids have all flowed out hydraulic pressure support chamber 48.It takes Certainly in the construction of sealing device 466, such as density of the density relative to relatively high density fluid of sealing unit 424, when close The volume that seal apparatus 466 enters the discharge unit 438 kept when its sealing state can be different.For example, working as sealing device 466 can keep the relatively small volume of discharge unit 438 when entering its sealing state.The entire volume of discharge unit 438 can also Hydraulic pressure support chamber 48 is flowed out before sealing device 466 enters its sealing state.

Once sealing device 466 enters its sealing state, may refrain from across sealed body 426 and main body interactive surfaces The fluid communication of 430 sealing interaction.It is assumed that actuating valve 52 is closed and thus remains under its sealing state, then it is hydraulic Support chamber 48 is sealed.In the case where hydraulic pressure support chamber 48 is sealed, seat support strut top 20 is opposite along direction C is reduced In seat support strut lower part 22 limitation of movement in the compressibility of hydraulic pressure support chamber 48.In the embodiment as shown, it seals Part 440 represents substantially all of hydraulic pressure support chamber 48, and only minimum compressibility will be possible.

In one embodiment, hermetic unit 440 represents the volume of the hydraulic fluid in hydraulic pressure support chamber 48, and Discharge unit 438 represents the volume of the air in hydraulic pressure support chamber 48.As one that discharge unit 438 is hydraulic pressure support chamber 48 When part, the compressible nature of air will imply that hydraulic pressure support chamber 48 is relatively compressible.In this case, seat support strut It can be moved in the case where not opening actuating valve 52 between top 20 and seat support strut lower part 22.Constitute discharge unit 438 The air of relatively small density is separated with the hydraulic fluid of relatively large density for constituting hermetic unit 440, and thus, it is possible to from liquid Pressure support chamber 48 selectively removes air.

Fluid communication by sealing element 476 is discharged may be alternatively located at another component of hydraulic pressure support chamber 48 Yu bicycle 10 Or between another component of seat component 15.For example, hydraulic pressure support chamber 48 can be by discharge sealing element 476 and another component stream Body connection, to promote the receiving of fluid and/or the recycling of fluid.It can also be arranged by the fluid that discharge sealing element 476 transmits It is put into atmosphere, i.e. external environment 100.

Figure 23 is the equal part cross-sectional view with an embodiment of seat component 15 for sealing device 466.In Figure 23 Exemplary into Figure 22 of example and Figure 16 the difference is that the construction of discharger 66 and bias-adjusted component 410 and It is not provided with floating piston 44.The embodiment can change.For example, the embodiment can have 66 He of discharger of Fig. 1 Bias-adjusted component 410 but do not have floating piston 44.Alternatively, the embodiment of Figure 16 may be configured as no floating piston 44。

Embodiment shown in Figure 23 to Figure 29 can keep the characteristic similar with aforementioned embodiments, this, which is depended on, has Gravity Separation between the fluid of different densities.For example, as aforementioned embodiments, relatively highdensity fluid oil will be It is collected when being connected to the gaseous fluid of relatively low density at the gravitational base of given chamber.The embodiment of Figure 23 to Figure 29 Also show the different configuration of bias-adjusted component 410.

Bias-adjusted component 410 can interact with the different configuration of removable bias regulator 412.For example, removable Bias regulator 412 can have rotatable cam to construct and can be not formed as a part of bias-adjusted component 410.It shows Removable bias regulator 412 includes cam portion 417, and cam portion 417 is configured to and adjusts 416 phase of reverse bias retainer Interaction.Cam portion 417 has the eccentric configuration relative to camshaft line N.

Figure 30 A to Figure 30 C shows an embodiment of the removable bias regulator 412 with cam portion 417 Different views.The removable bias regulator 412 shown includes axially being divided relative to camshaft line N by attachment recess 493 From the first surface of revolution 492 and the second surface of revolution 494.First surface of revolution 492 and the second surface of revolution 494 are configured to It is rotated relative to rotary interaction surface 411 around camshaft line N.Rotary interaction surface 411 can be by seat branch The annular inner surface that gap in column cap 18 limits.Equally, the first surface of revolution 492 and the second surface of revolution 494 are removable The annular outer surface of bias regulator 412.

Attachment recess 493 can be used for for removable bias regulator 412 being axially fixed relative to camshaft line N.For example, Attachment recess 493 is between the first fixation surface 495 and the second fixation surface 496.First fixation surface 495 and second is fixed Surface 496 can be configured to interact with another component, and removable bias regulator 412 is axial along camshaft line N Ground is fixed to seat support strut head 18 or another component.For example, spring-loaded ball detent or similar device (not shown) can quilts It is included in seat support strut head 18, to limit removable bias regulator 412 along the axial movement of camshaft line N, while not Removable bias regulator 412 is inhibited to surround the rotation of camshaft line N.

The cam portion 417 of removable bias regulator 412 is shown on cam orientation surface 498.Cam part 417 are divided can integrally or to be otherwise secured to cam orientation surface 498.Cam portion 417 is configured to and bias-adjusted Component 410 interacts, and is limited with setting by the relative position on the biased direction D and reverse bias direction E along second axis M Bias-adjusted component 410 position.Cam portion 417 is prejudicially constructed, so that at least two of bias-adjusted component 410 Position becomes easy.Cam portion 417 can be configured to the infinitely adjustable position of bias-adjusted component 410.Cam portion 417 The a limited number of discrete location of bias-adjusted component 410 can be also configured to.

The shown construction of cam portion 417 is configured to four discrete locations of bias-adjusted component 410.Bias-adjusted Each position of component 410 is limited by cam face and its at a distance from camshaft line N.In this embodiment, away from cam The bigger distance of axis N corresponds to more big displacement of the bias-adjusted component on biased direction D.Corner between cam face can It is chamfered to promote the rotation around camshaft line N.

The embodiment of cam portion 417 shown in Figure 30 A to Figure 30 C has the corresponding to the first cam distance Q One cam face 491, corresponding to the second cam face 497 of the second cam distance R, corresponding to the third of third cam distance S Cam face 499 and the 4th cam face 500 corresponding to the 4th cam distance T.Each of cam distance Q, R, S and T are equal It is related to the axial distance of the camshaft line N away from each respective cam surface 491,497,499 and 500.When each cam face 491,497,499 and 500 with adjust reverse bias retainer 416 engage when, adjusting reverse bias retainer 416 on biased direction D The distance shifted from camshaft line N will correspond to identical cam distance Q, R, S and T.

Figure 30 A to Figure 30 C shows an implementation of the tool there are four the cam portion 417 of discrete cam distance Q, R, S and T Mode.However, cam portion 417 can construct otherwise.For example, the first cam distance Q and third cam distance S can phases Together, and the second cam distance R and the 4th cam distance T can be identical.In the alternative embodiment, with adjusting interface 414 Hex key interface configurations make the removable rotation of bias regulator 412 will be effective between the two of bias-adjusted component 410 positions Ground switching.Bias-adjusted component 410 can be made in biasing side for example, rotating to the second cam face 497 from the first cam face 491 Inhibit the position moved of discharge component 474 from allowing to be discharged component 474 and shift to along the position that second axis M is moved on D.? In the example, then, being further rotated to third cam face 499 from the second cam face 497 can be by bias-adjusted component 410 Back to the position for allowing to be discharged the movement of component 474.

Rotating to the second cam face 497 from the first cam face 491 may include rotation by transition region 489.Transition region 489 can be the wedge angle between the first cam face 491 and the second cam face 497 or can be chamfered.In an embodiment party In formula, a possibility that the orthogonal configuration of transition region 489 can be used so as to rotate relative difficulty, such as reduce unexpected rotation.Another In one embodiment, the obtuse angle or chamfer configuration that transition region 489 can be used are so that rotation is relatively easy, such as increase user is adjustable Section property reduces abrasion.In yet another embodiment, the transition between the first cam face 491 and the second cam face 497 Area 489 is chamfered in order to be easy rotation, and another transition region has orthogonal non-chamfer configuration to limit unexpected rotation.

Figure 24 to Figure 26, which is shown, rotates removable bias regulator 412 so that the 4th cam face 500 and adjusting are reverse-biased Set the interaction of retainer 416.Reverse bias retainer 416 is adjusted as a result, to shift on the biased direction D along second axis M 4th cam distance T.This relatively long displacement on biased direction D corresponds on discharge bias unit 480 relatively Height preloads.The discharge bias unit 480 in helical spring construction shown is thus along biased direction D by relatively high biasing Power is applied on discharge component 474.Therefore, discharge component moves into the hydraulic branch of its unsealing state needs on the E of reverse bias direction The relative high pressure supportted between chamber 48 and biasing chamber 401 is poor.

Figure 27 to Figure 29, which is shown, rotates removable bias regulator 412 so that the first cam face 491 and adjusting are reverse-biased Set the interaction of retainer 416.Reverse bias retainer 416 is adjusted as a result, to shift on the biased direction D along second axis M First cam distance Q.This relatively short displacement on biased direction D corresponds on discharge bias unit 480 relatively Low preloading.The discharge bias unit 480 in helical spring construction shown thus will be relatively low inclined along biased direction D Power is set to be applied on discharge component 474.Therefore, it is hydraulic to move into its unsealing state needs on the E of reverse bias direction for discharge component Support the relative lower pressure between chamber 48 and biasing chamber 401 poor.

Figure 25 and Figure 28 show discharge bias unit 480 be respectively at relatively high bias force state and it is relatively low partially Component 474 is discharged when setting under power state to be under its actuating state or unsealing state.As in aforementioned embodiments, discharge Component 474 can be overcome by pressure difference enough between hydraulic pressure support chamber 48 and biasing chamber 401 by discharge bias unit 480 provide bias forces and be actuated under its unsealing state.The situation under its unsealing state is in sealing device 466 Under, the compressible fluid with relatively low density can preferentially flow out hydraulic pressure support chamber 48.In one embodiment, it seals Device 466 is configured to after generally all low density flows have flowed out hydraulic pressure support chamber 48 but in the highly dense of big volume It is sealed before degree fluid outflow hydraulic pressure support chamber 48.

Figure 26 to Figure 29 show discharge bias unit 480 be respectively at relatively high bias force state and it is relatively low partially Sealing device 466 is under its sealing state when setting power state.As in aforementioned embodiments, due to sealing unit 424 The compressible fluid of neutral buoyancy and relatively small density preferentially flows out hydraulic pressure support chamber 48, which can be by close Movement of the unit 424 on raising direction B is sealed to realize.Sealing device 466 prevents from further flowing out hydraulic pressure support chamber 48 simultaneously Connecting chamber 112 is flowed into via recirculation path 404.

Figure 24 to Figure 29 depicts the disengaging axes O deviated from the second axis from line M.Discribed construction has bias-adjusted The close-fitting first annular outer surface of component 410 extends in the first annular inner surface of seat support strut head 18 and with Centered on two axis M.Bias-adjusted component 410 also has and disengaging close-fitting second annular outer surface in surface 442.Disengaging Surface 442 can be the second annular inner surface of seat support strut head 18 and centered on passing in and out axes O.Second axis M and into The offset of axes O inhibits the relative rotation of bias-adjusted component 410 and seat support strut head 18 in this configuration out.Inhibit the phase Regulating system pressure can be come to replace adjusting valve deck convenient for the thread attachment part of installing and disassembly air pump (not shown) to rotation Power.

It can otherwise realize the anti-rotation feature of bias-adjusted component 410.For example, bias-adjusted component 410 can be in Existing polygonal structure is so as to the polygonal structure interaction with disengaging surface 442.Alternatively, bias-adjusted component 410 and into Surface 442 can be bonded to prevent the relative rotation between them out.

Imagine other constructions of bias-adjusted component 410.For example, the embodiment of implementable ratchet or plunger-type.? In alternative embodiment, removable bias regulator 412 can be omitted.In this embodiment, discharge bias unit 480 can be It is not adjustable.For example, bias-adjusted component 410 can be replaced with the component not being adjustable.It is such to replace begging for about Figure 31 By.
